PUMPING-ENGINE.

SPECIFICATION forming part of Letters Patent No. 263,694, datedSeptember 5, 1882. Application filed May 8, 1882. (No model.)

To all whom it may concern:

Be it known that I, HARVEY F. GAsK LL, of Lockport, in Niagara county,New York, have invented certain new and useful Improvements inPumping-Engines, of which the following is a specification.

The ordinary direct-actin g steam-pumps are of a low efficiency as compared with crank and fly-wheel engines, while the latter are expensiveto build as compared with the former.

It is the object of my invention to secure the advantages of both theseconstructions. This I do by certain novel combinations of parts, which Ishall particularly point out in the claims at the end hereof.

In the drawing I haveshown a longitudinal section of an enginecontaining my improvements. It represents a horizontal pumping-engineofthe compound or Woolf type. Briefly described this engine consists of adirect-acting steam-pump, a crank and fly-wheel engine mounted on thedirect-acting pump as a foundation, and av beam connecting the twotogether.

A is one of the steam-cylinders; at, its piston; B, the pump in linewith cylinder A; b, the pump-plunger; G, the pump and pistonrod; K k,the suction-pipe and box, and L l the discharge of the pump. M is anair-chamber on the discharge. D is a guide-bar, and d a cross-head onthe rod 0. E is another steam-cylinder mounted on cylinder A as a bed.The two'cylinders E and A are arranged to operate as high and lowpressure, respectively, the cylinder E exhausting into cylinder A. e isthe piston of cylinder E; I, its piston-rod; h, a cross-head moving on aguide-bar, H. dis a beam oscillating on a center at 7', and connected atone end with rod I by linkz' and at the other end with rod 0 by link 0.As pistons a and c are connected to opposite ends of the beam J, theywill move in opposite directions, the piston a making a backward strokewhile e makes a forward stroke, and vice versa. By this arrangement I amenabled to conduct the exhaust-steam from cylinder E directly intocylinder A without the loss of pressure that results from long tortuouspassages or an intermediate receiver. F is a fly-wheel; G, the crank; g,the pitmanconnection between the crank and. the piston c. The box f ofthe crank-shaft is mounted on the pump-box l as a foundation.

The air-pumps may be driven from the beamshat'tj.Ihavenotthoughtitnecessarytoshow them or the valves, as any suitablevalves may be used, and their presence in the drawing would simplycomplicate it.

I prefer ordinarily to arrange two of these machines side by side with asingle crankshaft, the cranks being at right angles, thus forming aduplex engine.

What I claim is-- 1. The combination of the two steam-cylinders mountedone upon the other, the pump in line with one of said cylinders, thecrank and fly-wheel mounted on the pump, and the beam connecting thewhole into one machine, substantially as described.

2. The combination of the two steam-cylinders mounted one upon theother, the beamconnection between the two, the pump in line i with oneof said cylinders, and the crank and HARVEY F. GASKILL.
